Portulaca plant named ‘Cindy’

ABSTRACT

A new and distinct cultivar of Portulaca plant named ‘Cindy’, characterized by its outwardly spreading and trailing plant habit; freely branching growth habit; relatively rapid growth rate; double flower form; and yellow and orange bi-colored flowers.

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Portulaca grandiflora cultivar Cindy.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Portulaca plant, botanically known as Portulaca grandiflora, and hereinafter referred to by the name ‘Cindy’.

The new Portulaca is a product of a planned breeding program conducted by the Inventor in Naaldwijk, The Netherlands. The objective of the breeding program is to create new Portulacas with interesting flower forms and flower colors.

The new Portulaca is a naturally-occurring whole plant mutation of an unnamed selection of Portulaca grandiflora, not patented, that was discovered and selected by the Inventor during the summer of 1999 in a controlled environment in Naaldwijk, The Netherlands, on the basis of its yellow and orange bi-colored double flowers.

Asexual reproduction of the new cultivar by cuttings taken in a controlled environment in Naaldwijk, The Netherlands since 1999, has shown that the unique features of this new Portulaca are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Cindy have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and culture such as temperature, light intensity, and daylength without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Cindy’. These characteristics in combination distinguish ‘Cindy’ as a new and distinct cultivar:

1. Outwardly spreading and trailing plant habit.

2. Freely branching growth habit, dense and full plants.

3. Relatively rapid growth rate.

4. Double flower form.

5. Yellow and orange bi-colored flowers.

In addition to flower coloration, plants of the new Portulaca differ from plants of the parent selection and other Portulaca cultivars known to the Inventor in the following characteristics:

1. Plants of the new Portulaca are not as compact as plants of the parent selection and other known cultivars of Portulaca.

2. Plants of the new Portulaca have a more rapid growth rate than plants of the parent selection and other known cultivars of Portulaca.

3. Plants of the new Portulaca have double flowers whereas plants of the parent selection and other known cultivars of Portulaca have single flowers.

Plants of the new Portulaca differ from plants of the cultivar Sleeping Beauty, U.S. Plant patent application Ser. No. 10/016,878 filed concurrently, and the cultivar Snow White, U.S. Plant patent application Ser. No. 10/016,879 filed concurrently, primarily in flower coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Portulaca.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Cindy’.

The photograph at the bottom of the sheet comprises a close-up view of a typical flowering plant of ‘Cindy’ showing the foliage and flowers.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following observations and measurements were planted into 15-cm containers and grown for about four months during the summer in a glass-covered greenhouse in Aalsmeer, The Netherlands. During the production of the plants, the day and night temperatures averaged 20° C.

In the following description, color references are made to The Royal Horticultural Society Colour Chart, Edition 1995, except where general terms of ordinary dictionary significance are used.
